OpenPGP keys are made up of a single primary key, and any number of subkeys (including, in some cases zero).  This allows the user to pick particular key types for particular purposes.  For example, a common usage is to use the primary key for signing things and the subkey for encrypting things.

As to your other question, it was asked earlier this week.  See http://www.gossamer-threads.com/lists/gnupg/users/53692
